Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on. | No power or loose connection. | Check if the USB-C cable is securely connected to both the light and the power source. Ensure the power source is active. |
| Light flickers. | Unstable power supply. | Connect the light to a stable 5V-1A USB power source, such as a PC's USB port or a dedicated wall adapter. Avoid USB hubs or mobile power banks. |
| Auto-dimming not working correctly. | Light sensor obstructed. | Ensure nothing is blocking the light sensor on the light bar. |
| Screen glare or reflection. | Incorrect light positioning. | Adjust the angle of the light bar to ensure the non-asymmetric optical design directs light onto your desk, not the screen. |
